There’s an emote trick you can try if you want to confuse your opponent and possibly make him use his flash or heal. Especially if at low health.
It is successful when playing as support or ADC at bottom lane and as Blue team. All you have to do, is to go near the bush, the one at the corner of the river best, and use an emote, preferably an emote that shows your jungler. The thing is that at first glance for milliseconds it looks like your jungler comes out of the bush for a gank.
If you try it, please write your feedback.
